Powerful Communication

Body language -- No matter how knowledgeable you are, if your posture doesn't reflect confidence, you will not command respect.

Vocal tone and pace -- Maintain an even tone of voice, with a low pitch and resist the temptation to speak faster when feeling flustered.

Grammar and language -- Be concise and economical with words. Using filler words like 'I mean', 'you know' and 'I think' will weaken your authority.

Professional attire -- Wear business suits and dresses that reflect your corporate style and good taste.

Appropriate use of laughter and humor -- Avoid the habit of giggling when nervous or uncomfortable. A person who constantly smiles and laughs unnecessarily is less likely to be trusted in serious situations.
